[Laser] Lenses?

Fri, 15 Mar 2002 17:50:57 -0800

OK, I think  I have enough good lense sources, how about detectors.  FOr my
project I need something fairly boradbanded in the IR range, but something
that cuts off just above the red spectrum, a simple detector just a couple
connections, preferably cheap but of reasonable quility.  Any ideas?  How re
those units that All Electronics was selling?  Any Good?  Any
specifications?
